FullText example madness !
Posted by: Richard Shea

Hi - I've just followed the FULLTEXT example at . I'll post it here for ease of reference ...

CREATE TABLE articles (
title VARCHAR(200),
body TEXT,
FULLTEXT (title,body)

INSERT INTO articles (title,body) VALUES
('MySQL Tutorial','DBMS stands for DataBase ...'),
('How To Use MySQL Well','After you went through a ...'),
('Optimizing MySQL','In this tutorial we will show ...'),
('1001 MySQL Tricks','1. Never run mysqld as root. 2. ...'),
('MySQL vs. YourSQL','In the following database comparison ...'),
('MySQL Security','When configured properly, MySQL ...');

SELECT * FROM articles
WHERE MATCH (title,body)

... my problem is that the example shows that SELECT returning two rows ('DataBase' and 'database') but I only get one row ('database') !

The example doesn't demonstrate what collation the table ended up with but I have ended up with latin1_general_cs on the title and body columns.

My version of MySQL is 5.1.39-log and the connection collation is utf8_unicode_ci .

I'd be really grateful is someone could suggest why my experience differs from the example in the manual !

In case it's significant here's a dump of the server variables.

Be grateful for any advice.
